High Frequency Material PCB Assembly

Shenzhen Cirket Electronics Co., Ltd, yankho lanu loyimitsa kamodzi pazosowa zanu zonse za OEM ndi ODM PCB ndi PCBA. Kukhazikitsidwa mu 2009, takula kukhala otsogola opereka chithandizo chokwanira chamakasitomala padziko lonse lapansi. Ndi mizere 9 ya SMT ndi mizere iwiri ya DIP, tili ndi kuthekera kosamalira mbali iliyonse yakupanga, kuyambira pakukulitsa ndi kugula zinthu, kusonkhanitsa ndi kukonza.

PCB yothamanga kwambiri (Printed Circuit Board) imatanthawuza mtundu wa bolodi lopangidwa kuti lizigwira ntchito pama radio frequency (RF) kapena ma microwave frequency. Ma frequency awa nthawi zambiri amachokera ku mazana a megahertz (MHz) kupita ku ma gigahertz angapo (GHz) ndipo amagwiritsidwa ntchito kwambiri pamakina olumikizirana opanda zingwe, makina a radar, maulumikizidwe a satellite, komanso kukonza ma siginoloji othamanga kwambiri.

Ma PCB othamanga kwambiri ali ndi mawonekedwe angapo osiyana ndi mapangidwe ake poyerekeza ndi ma PCB wamba:

1. Kusankha Zinthu: Ma PCB othamanga kwambiri nthawi zambiri amagwiritsa ntchito zida zapadera zokhala ndi magetsi abwino kwambiri kuti achepetse kutayika kwa ma siginecha ndikusunga kukhulupirika kwa ma siginecha pama frequency apamwamba. Zida zodziwika bwino zimaphatikizapo magawo a PTFE (Polytetrafluoroethylene) monga Teflon, komanso ma laminate okwera kwambiri monga FR-4 okhala ndi dielectric properties.

2. Low Loss Dielectric:Zida za dielectric zomwe zimagwiritsidwa ntchito mu ma PCB othamanga kwambiri zimasankhidwa chifukwa cha kuchepa kwa dielectric constant (Dk) ndi low dissipation factor (Df), zomwe zimathandiza kuchepetsa kutsika kwa chizindikiro ndi kupotoza pamaulendo apamwamba.

3. Kulepheretsa Kuwongolera: Ma PCB othamanga kwambiri nthawi zambiri amafunikira kuwongolera bwino kwa zolepheretsa kuti zitsimikizire kufalikira kwa ma siginecha ndikuchepetsa kuwunikira. Tsatani m'lifupi, makulidwe a dielectric, ndi masinthidwe osanjikiza amapangidwa mosamala kuti akwaniritse zomwe mukufuna.

4. Kuyika pansi ndi kuteteza: Njira zoyenera zoyatsira pansi ndi zotchinjiriza ndizofunikira kwambiri pamapangidwe apamwamba a PCB kuti muchepetse kusokoneza kwamagetsi (EMI) ndikuwonetsetsa kukhulupirika kwa ma sign. Ndege zapansi, zolondera, ndi zotchingira zotchingira zimagwiritsidwa ntchito kuchepetsa kuphatikizika ndi phokoso.

5. Kapangidwe ka Mzere Wotumizira: Ma siginecha apamwamba kwambiri pa ma PCB amakhala ngati zingwe zotumizira m'malo mongotsatira magetsi. Mfundo za kapangidwe ka mizere yopatsirana, monga mizere yopingasa yoyendetsedwa, masinthidwe a mikrostrip kapena mizere, ndi njira zofananira ndi ma impedance, amagwiritsidwa ntchito kukhathamiritsa kukhulupirika kwa ma siginecha ndikuchepetsa kuwonongeka kwa ma sign.

6. Kuyika ndi Njira:Kuyika mosamalitsa ndikuwongolera zigawo ndi kutsata ma siginecha ndikofunikira pamapangidwe apamwamba kwambiri a PCB kuti muchepetse kutalika kwa njira, kupewa kupindika kwakuthwa, ndikuchepetsa zotsatira za parasitic zomwe zimatha kutsitsa mtundu wazizindikiro.

7. Zolumikizira Zapamwamba:Zolumikizira zomwe zimagwiritsidwa ntchito mu ma PCB othamanga kwambiri zimasankhidwa chifukwa cha mawonekedwe awo ofananirako komanso kutayika pang'ono kuti achepetse kuwunika kwa ma siginecha ndikusunga kukhulupirika kwa ma siginecha pama frequency apamwamba.

8. Kasamalidwe ka Kutentha: M'mapulogalamu ena amphamvu kwambiri, kuwongolera kutentha kumakhala kofunika kwambiri kuti tipewe kutenthedwa kwa zigawo ndi kusunga magwiridwe antchito odalirika. Njira zoyatsira kutentha, njira zotenthetsera, ndi njira zowongolera kutentha zimagwiritsidwa ntchito kuti zithetse kutentha bwino.
